m'risxronme nnvron- FOR AUTOMOBILES.

To all whom it may concern:

Be it known that 1,,ROBERT A? Moons, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Antiskidding Devices forAutomobiles, of which. the following is a specification.

This invention relates to devices to counteract the tendency ofautomobiles to skid, thereby preventing accidents which commonly occurdue to skidding.

For a full understanding of the invention reference is' to be had to thefollowing detail description and the accompanying drawings, in wh1ch--Figure 1- is a side view of a conventional form of automobile to whichthe improve ment is applied; Fig. 2 is a diagrammatic representation ofthe rear wheels and framework between the wheels To which theimprovement is connected; Fig. 3 is a bottom plan ,view of a detailhereinafter described, and Fig. 4 isatransverse section of the same.

Throughout the following description and on the several figures of thedrawings similar parts are referred to by like reference characters.

A indicates an automobile with the usual rear wheels B and front wheelsC. The machine may be propelled in any suitable manner and if the rearaxle is to be the progelling e incased in a tubular casing orif the rearaxle is stationary and the wheels are driven by other means the casingmay not be required. To the rear casing or axle are connected .aplurality. of lamp members 11, preferably two adjacent ch end of theaxle, the same being spaced apart sufficiently to provide a strongabutment for a hanger 12 pivoted thereto. Thev "hanger as viewed rom therear comprises a plurality ofsubstantially parallel legs 13 and 14through which a pair of bolts 15 or the like may be passed ,to securethe hanger'to the pair of clamps 11. The hanger also includes atransverse or diagonal brace 16 which serves also as point of connectionfor a chain 17 connected at its opposite end to any suitable operatingmeans such as a lever 18. It will be understood that a hanger andassociated parts will be provided for each side of the vehicle, eachoperated by its own lever. A

substantial spring 19 may be interposed between the ends of the chain 17in order to prevent breakage of the hanger when in use, due to strikingof a stone or other obstruction.

The hangeris intended to be suspended normally out of contact with thepavement by any sui ble means such as a spring 20, strong'enough forthis purpose but not sufficient'ly strong to resist the proper opefi'la- 1e spring 20 is connected at one end to the hanger and at itsother end to any convenient stationary part of the vehicle.

The lower portion 12 of the'hanger extends outwardly toward the adjacentwheel and terminates in a foot 21. The foot 21 or portion of the hangerwhich is adapted to engage with the pavement is arranged at an angle tothe main part of the hanger and .is substantially flat on the bottomexcept as hereinafter set forth. The angle at which the =foot isdisposed-to the hanger is such I thatwhen the hanger is drawn upon bythe lever 18 and chain 17 the foot Wlll engage the pavementsubstantially throughout its length. As shown in the detail views thefoot on the lower face is provided with a series of angular ridges 21.These ridges are straight and parallel but arranged atan angle to thegeneral length of the foot, and are directed substantilly toward thefront wheel on the opposite side of the vehicle. It being well knownthat the skidding of a vehicle is most dangerous while the machine isrunning at a rapid speed. 'If the machine should skid, say toward theright as viewed in Fig. 2 the hanger 12 should be depressed on that sideof the machine and held substantially in contact with the pavement, sothat the momentum of the machine in a forward direction will insure thatthe diagonally disposed ridges 21' will cause the machine or tend tocause the machine to approach again the proper path, the effect of theridges being'similar to the effect of a skate on ice withrespect to thedirection in which the machine'will be propelled. With respect totheefiect of the hanger and foot as to checking or stopping the vehiclefrom going in'other directions than the direction indicated by theridges will be similar to a ground brake. Furthermore, unlike certainother devices heretofore proposed for the.

v to the main portion general purpose of this device it will notlmaterially damage or gouging into it.

The several parts of this device may be made of any suitable materialsand the specific form and arrangement thereof may be varied somewhatwithout departin from the spirit of the invention hereinafter claimed.

I claim 1. In combination with an automobile including a body and a rear'ving wheel, an anti-skidding device comprising a hanger, means tonormally carry the hanger elevated from the bottom of the wheel, andmeans to depress the hanger so as to engage the roadway adjacent thebottom of the wheel, said hanger including a foot disposed at an angleof the hanger and provided on its lower surface with a series ofstraight parallel ridges arranged at an angle to the general directionof the foot.

2. The hereindescribed anti-skidder for automobiles comprising a pair ofclamps, a hanger including a pair of substantially parallel legspivotally connected to said clamps, means to normally hold the hangerwith. its opposite end elevated from the ground, and foot operatedmeansto draw the hanger down and forwardly into 'enthe pavement by cuttingposed at an angle rfoot extending gagement with the ground, said hangerincluding 'a substantially straight foot disto the main portion of theha r, said foot being rovided with means ten ing to direct the vehicleback toward its proper path. I

3. The combination with an automobile including a body, a frame andsupporting wheels, of an anti-skidder associated with one of the rearwheels, said anti-skidder ineluding a pair of clamps connected rigidlyto said frame, a hanger includi a pair'of legs pivotally connected tosaid c amps, the lower portion of the hanger extending at an angleoutwardly toward the wheel, means to normally suspend the hanger from'the ground, the hanger including a sharp tdged at an angle to the mainportion of the hanger and adapted to resist skidding and to tend to proe1 the vehicle back to its normal path, and foot operated meansconnected withsaid vehicle body to draw the hanger down lnto engagementwith the ground.'
